The crew's dynamic in the disaster was slightly exaggerated for dramatic effect. In the movie there's a strange tension between Bill Paxton and Kevin Bacon which culminates into a shouting match trying with them at each other's throats. In real life they were completely calm and cool as cucumbers focusing on the task in hand and troubleshooting their dilemma.

Other than that small element, I actually admired the historical accuracy of this movie. The command module and lunar module were exact replicas of the real thing down to the actual switches and knobs and they accurately corresponded to the real "button presses" in several scenes when they are stirring their O2 tanks and resetting electrical transfer busses.

This...

The US version absolutely has it's moments and I couldn't imagine any better casting to the Michael Scott role than Steve Carell, but the UK version is far better at delivering humor and emotion at a much darker level. Ricky Gervais is able to make me cringe at such a visceral level, and some of the scenes were just downright depressing.

US version = wholesome laughter.

UK version = dark laughter.

Knowing QT's style, it would be someone completely unexpected out of left fucking field. So cast my vote for that little Crazy 88 kid that Kiddo spanked and sent home.
